With the ability to input complex equations and output fractions as well as decimals, this calculator produces math that looks like the math on your paper.
This makes it much more suited for higher mathematics in university and school than your average mobile calculator (in case you forgot yours again and only have your phone), especially if you have become accustomed to the controls from a young age.
t is built completely from scratch using pure web technologies and packaged into both an Android app as well as a Flatpak package for use on Linux devices.
This project uses math.js
